Sensorless BLDC Control

Jump To

Overview

Sensorless BLDC control under ultra-high supply voltage (up to 18V) is now widely needed in tones of applications such as drone ESC, DC fan etc. This reference design is based on NXP's highly-integrated 8-bit S08 microcontroller MC9S08SU8/16. With its compact design, the BLDC control board can achieve great performance at a very low cost.

With the full schematic available, the reference design can be used as an evaluation kit for S08SU MCU, a reference for creating one's own BLDC control-related design, as well as an applicable three-phase sensorless BLDC solution.
